2019年12月1日 · A novel kind of non-precious metal nanohybrid FeNC-900 is synthesized by hard-template with pyrolysis method using Fe-doped ZIF-8 as the precursor. The FeNC-900 has a superstructure of Fe, N co-doped carbonaceous hollow spheres crosslinked by some self-grown carbon nanotubes.

2023年2月15日 · We found out that the FeNC-700 shows the most prominent adsorption capacity for DBT with 7.48 mg of sulfur per gram adsorbent, being slightly higher than that of FeNC-800 (blue curve, 7.31) and FeNC-900 (red curve, 7.05).

2021年10月4日 · FeNC-900 also shows better durability and good methanol tolerance than those of commercial Pt/C. Besides, FeNC-900 exhibits an outstanding specific capacity of 258 F g−1 at 1 A g−1 for supercapacitor. The method presented here may provide a cost-efficient approach to fabricate carbon-based materials for ORR and supercapacitors.
